Performance Evaluation of Multiple Unmanned Aerial Vehicles Operating in General Regime with Shortage of Maintenance Facilities  [PDF]
Joseph Kreimer
Journal of Computer and Communications (JCC) , 2016, DOI: 10.4236/jcc.2016.410008
Abstract: We consider a real-world problem of military intelligence unit equipped with multiple identical unmanned aerial vehicles (UAV) responsible for several regions (with requests of real-time jobs arriving from independent sources). We suppose that there are no ample maintenance facilities, allowing simultaneous treatment of all vehicles if necessary. Under certain assumptions, these real-time systems can be treated using a queueing theory methodology and/or as Markov chains. We show how to compute steady-state probabilities of these systems, their performance effectiveness, and various performance parameters (for exponentially distributed service and maintenance times of UAVs, as well as tasks duration and their arrival pattern).
A qualitative analysis of facilities maintenance — A school governance function in South Africa
MI Xaba
South African Journal of Education , 2012,
Abstract: I analysed school facilities maintenance, a school governance function in South Africa. Qualitative interviews were conducted with 13 principals and three deputy principals as coordinators of this function at their schools. The interviews were purposively and conveniently selected to gather data regarding school facilities maintenance and gain insight into the challenges this function presents to schools and their governing bodies. Findings indicate that schools generally do not have organisational structures for planned facilities maintenance, nor do they have policies on facilities maintenance. Evidence of facilities maintenance at schools mainly relates to concerns with facilities repairs, (mostly “as the need arises”) and general campus cleanliness; mostly with emergency and corrective forms of maintenance as opposed to crucial preventive maintenance. Therefore, there is a need for interim facilities maintenance committees and, in the long term, a whole-school approach to facilities maintenance that makes facilities maintenance a strategic lever for school functionality.

Abstract: The philosophy of every maintenance practice and operation in any organization is usually to provide a structurally sound and aesthetically appealing environment throughout the life of a property. Maintenance has generally been referred to as all works carried out to keep and restore an item to a currently acceptable standard. This work evaluates the performance of facilities maintenance management in the maintenance of sport complexes in South–West Nigeria. The study research method includes physical observation, administration of questionnaires to measure performance. In order to gather information, structured questionnaires were administer at the study area (the six stadia covered), the management staff, the maintenance staff and the user of the facilities in each of the stadia, covering kiosk owner, sport men and women, spectators, and lover of sports. The study revealed some factors affecting performance in the maintenance of sports complexes among which are: funding, organizational structure, political factors, ownership types, and security. The study concluded that it is only when adequate fund is provided and fully utilized in the maintenance of sport complexes that one will enjoy the initial investment in them and the consequent accruing benefits from the complexes will be achieved. The study recommended among others facts that the government should set aside part of her annual budget to maintenance of the sport complexes so as to ensure their fitness and world class standard at all time which will consequently reduce the operating cost and increase the revenue generating capacity of the stadium.
Model of Maintenance Planning Based on Trend of Machines Failures with Two Priorities  [PDF]
Erik Prada, Alena Pe?ková, Michael Valá?ek
World Journal of Engineering and Technology (WJET) , 2015, DOI: 10.4236/wjet.2015.34021
Abstract: In this article we are discussing the suggestion of planning maintenance in such situation that we have failures in database of failures and maintenance registered also according to type of failure— priority or non-priority. We are assuming that maintenance must be mainly oriented on avoiding major failures of machines. The effect of maintenance manifests with delay and is dependent on development of failures. We express this problem as linear programming task that is solvable with Solver-extension of application Excel. We demonstrate the suggested solution on example of failures of machines between years 2010 and 2012.

Journal of Agricultural Science , 2012, DOI: 10.5539/jas.v4n3p71
Abstract: This paper presents the capability of tractor operators in performing repair and maintenance of small tractors, the availability of service and repair facilities at the farm level, and the manner of the operators in maintaining their tractors. Data are based on field visits and interviews with 65 tractor operators from 6 villages collected in three regencies of Riau Province. The results show that most operators lack the technical skill to service and repair tractors due to insufficient training, specific education, and work experience. Inadequate repair and maintenance facilities, such as workshops, mechanics, and spare part depots cause delays in repair work and raise the price of spare parts in the survey areas. Farmers do not keep accurate service records and most of them disregard proper maintenance and service of their tractors, such as changing engine oil without following the manufacturer’s recommendations. Provincial governments should provide training facilities and a program to improve the technical knowledge and skills of the operators and local mechanics. Repair and maintenance facilities should be established in village areas to guarantee timely repair in case of breakdowns and to make spare parts available at low price. The operators should keep service records accurately and adhere to maintenance and service schedules according to the manufacturer’s instructions. They should also be encouraged to properly service and maintain their tractors.

Mathematics , 2012,
Abstract: The ample hierarchy of geometries of stables theories is strict. We generalise the construction of the free pseudospace to higher dimensions and show that the n-dimensional free pseudospace is \omega-stable n-ample yet not (n+1)-ample. In particular, the free pseudospace is not 3-ample. A thorough study of forking is conducted and an explicit description of canonical bases is exhibited.
